WAXED-THREAD SEWING.

SPECIFICATION forming part of Letters Patent No. 268,708, dated December 5, 1882.

To all whom it may concern Be it known that I, DANIEL MILLS, a citi-' zen of the United States, and a resident of Philadelphia, Pennsylvania, have invented an Improvement in Waxed-Thread Sewing, of which the following is a specification.

The object of my'invention is to dispense with the usual appliances used in connection with wax-thread sewing-machines for heating the thread, and thereby partially melting the wax with which the thread is coated and impregnated; and this object I attain by causing the thread to pass through benzine or other evaporative solvent of the wax.

In the accompanying drawing is represented a side view of a wax-thread sewing-machine, illustrating the mode of carrying my invention into eli'ect.

To the stationary arm A of the machine is attached a small cup or reservoir, B, containing the liquid solvent, the cup being furnished with a hinged cover, a. The waxed thread tr passes from a spool, D, and in contact with iollers, which constitute no part of my present invention, through acontracted orifice, d, in the top ot'the cup, the said orifice being flared both above and below. Thence the thread passes under a small roller, 6, on the bottom of the cup, and thence through the contracted outlet 1 to that part of the machine where the stitching takes place.

As wax-thread sewing-machines differ in construction and general conformation, difi'erent formsof cups and different locations for the same may be called for; but in all cases Application filed September 22, use. (No model.)

| the cup must be so constructed and situated that the waxed thread can be directed through its contents, and the cup should be closed, exceptin g at the orifices through which the thread passes, in order to prevent, as far as possible, the evaporation of the solvent; for I preferin all cases that the solvent should. be of an evaporativc character, so that it may not form a permanent ingredient of the wax, but may disappear after the stitching has taken place. I have found in practice that benzi'neis an excellent solvent, as it so acts on the wax of the thread as to render the latter flexible and reduce it to the condition which in ordinary waxthreadsewing-machines is due to the application of heat. I do not, however, desire to restrict myself to benzine or any other specific solvents, as there are many other liquid hydr0 carbons which will serve the desired purpose; nor do I desire to restrict myself to any specific means of applying the solvent.

I claim as my invention-- As an improvement in macllinesewing with waxed thread, the mode, substantially as described, of subjecting the said waxed thread to the action of an evaporative liquid solvent of the wax.

In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.
